Re: Lenovo T520i X11 Intel i810 "static display" issue

In response to a previous thread:

Dr. Mobius, Bill Brelsford, et all:

Did anyone find a solution or even a cause for this "static display"
problem upon resume from suspend?

I see that Martin Steigerwald claims that upgrading to 3.0 solves the
problem, but it hasn't solved the problem for me- I am running 3.1.0-rc1
with all upgraded packages on my Thinkpad T520 and the problem persists.
In looking around on the Internet I see that others have the same problem,
and _sometimes_ upgrading mysteriously helps, but no one seems to know a
definitive answer.

I would appreciate any help anyone can offer.
